Midterm Outcomes of Angioplasty for Pediatric Renovascular Hypertension

PurposeTo evaluate the midterm outcomes of percutaneous transluminal renal angioplasty (PTRA) for pediatric renovascular hypertension (RVH).Materials and MethodsThe clinical data of patients who underwent PTRA for RVH in the authors’ hospital from 2012 to 2019 were retrospectively analyzed. Postprocedural blood pressure, glomerular filtration rate (GFR) of the affected kidney, restenosis, and complications were closely monitored.ResultsPTRA was performed in a total of 30 children (20 boys and 10 girls), with a mean age of 7.3 years ± 0.7 (range, 40 days to 13.9 years) and a mean weight of 25.0 kg ± 2.3 (range, 3.4–53 kg). The median follow-up period was 26.5 months (range, 1 month to 7.5 years). Technical success was achieved in 26 (86.7%) of the 30 patients. Restenosis developed in 3 patients (10.0%). Only 1 patient underwent stent implantation, and the stent fractured 8 months later, requiring further intervention. There were no other complications. In terms of clinical benefit of blood pressure control after the initial PTRA procedure, 15 patients (50%) were cured and 7 patients (23.3%) showed improvement. There was no significant difference in the etiology, lesion location, and lesion length between patients with clinical benefit and failure (P = .06, P = .202, and P = .06, respectively). GFR of the affected kidney was significantly improved from 19.9 mL/min ± 11.2 to 38.1 mL/min ± 11.9 at the 6-month follow-up after PTRA (P < .001).ConclusionsThe overall results of PTRA for pediatric RVH caused by different etiologies are promising. PTRA not only provided a clinical benefit of blood pressure control in 73.3% of the patients but also significantly improved the function of the affected kidney.     

急性心肌梗死急诊介入治疗的临床评价

目的探讨急诊经皮冠状动脉介入治疗术(PCI)对ST段抬高型急性心肌梗死(STAMI)的治疗价值。方法STAMI46例,在发病12h内行急诊冠状动脉造影及直接冠脉支架置入术(DS)或预扩张后支架置入术(PS),观察术中心律失常发生情况,术后TIMI分级、心电图,出院前左室射血分数(LVEF)和住院期间主要不良心脏事件(MACE)等。结果DS组与PS组各项指标无差异,44例达TIMI3级,成功率达95.7%,ST段回落率67.4%,平均LVEF(49.4±9.46)%,术中心律失常发生率21.7%,无MACE发生。结论对于发病12h的STAMI患者,行急诊PCI,可开通梗塞相关动脉(IRA),改善心肌再灌注和近期预后。     

国外经皮冠状动脉腔内成形术后留置动脉鞘管的护理进展

Effect of Shuxinyin (舒心饮) on In-Stent Restenosis after Coronary Artery Stenting

Objective: To evaluate the effect of anti-platelet regimens and it's combination with Shuxinyin (SXY, 舒心饮,) on in-stent restenosis after stent implantation. Methods: Forty-four patients with successful stent implantation in a coronary artery were randomly assigned to the treated group (n=20) and the control group (n=24). The treated group received: SXY and anti-platelet therapy. The control group were treated with anti-platelet regimens only. Platelet activation was assessed before and immediately after the stenting by flow cytometry, the expression of P-selectin (CD62P) and glycoprotein(GP) Ⅱb/Ⅲa receptor. It was reassessed on the 30th day after stenting. Plasma fibrinogen (Fg) and C-reaction protein (CRP) were measured by biuret and laser scattering turbidimetry respectively at the same time. Observation was made on the scoring of the symptoms of Qi deficiency syndrome, Qi-Yin deficiency syndrome and blood stasis syndrome in the two groups. Differences between groups were compared. Results: Compared with the control group, combination with SXY and anti-platelet therapy was remarkable in reducing plasma CRP (P<0.05), and also with the tendency to decrease plasma Fg, GPⅡb/Ⅲa and CD62P. It could also evidently decrease the scoring of Qi-Yin deficiency syndrome, Qi deficiency syndrome and blood stasis syndrome after stenting (P<0.05, 0.01, 0.01) respectively. Follow-up survey found 40% relapse of angina pectoris with 4 cases of in-stent restenosis proved by angiography in the treated group. But the relapse of angina pectoris in the control group was 67% with 2 cases of myocardial infarction (MI), 7 cases of in-stent restenosis proved by angiography and one death. Conclusions: Combination with SXY and anti-platelet regimens can prevent stent thrombosis and in-stent restenosis after stent implantation, and it seems superior to anti-platelet therapy only.
